We divide 867798 by 78
We want to figure out the number of times 867798 can be divided by 78.

Step 1:
78 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 78

Step 2:
78 can be fit into 86 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 78 away from 86, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 78

Moving on to step 3:
If we divide 87 by 78, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 9 after subtracting 78 from 87.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 78

Step 4:
97 divided by 78 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtract 78 from 97 to get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 78

Advancing to step 5:
78 goes into 199 2 times with a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 1112.0
Subtracting 156 from 199 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 78

On to step 6:
78 can be fit into 438 5 times, resulting in a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 11125.0
If we take 390 away from 438, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 11125.6
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
78 goes into 120 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 11125.61
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
420 divided by 78 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 11125.615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 11125.6153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
If we divide 660 by 78, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 11125.61538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
If we divide 360 by 78, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 11125.615384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 11125.6153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 11125.61538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 11125.61538461 and a remainder of 4.2e-08.
